Connectors¶
Another idea that arose was the idea to connect craft sticks together, much like in the second catapult prototype as described in the catapult build process, except in a more structured manner.
Designing these connectors started from the Pop Vertex repository by Bas Pijls. These were adjusted to create corner connectors:
After this initial version was printed we adopted the technique “Rapid Prototyping”. In one day we went over five prototypes adjusting parameters like height of the gap, width of the gap, amount of wall and top/bottom layers, and also added a small addition to the design by adding small grip strips.
The added beams were simply subtracted from the beams that created the holders:
translate([0,1.5,-1.3]){
rotate([0,3,0]){
cube([10,1,1], center=true);
}
}
translate([0,-1.5,-1.3]){
rotate([0,3,0]){
cube([10,1,1], center=true);
}
}
Final Cura Settings:
- 0.12 layer thickness- 2 wall layers
- 5 top/bottom layers
- 10% infill
The final result is also quite sturdy:
We did later discover that this sturdiness is sadly not present in the horizontal axis. Due to the layers forming, that axis splits more easily. The design can be adjusted for this.
